rs1154510, also known as c.97G>A, p.Ala33Thr and A33T, represents a SNP in the HPD gene on chromosome 12.

Although the rs1154510(A) minor allele is listed in ClinVar as pathogenic as a dominant mutation leading to hawkinsinuria, this seems quite unlikely given that the frequency of this minor allele is around 10 - 15% in most populations.
